Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is characterized in that a game ball launching mechanism is installed in a window portion of a frame formed by connecting horizontal and vertical members in a rectangular shape. The present invention relates to a pachinko machine including a front frame provided with a firing mechanism operating section and the like.

<Prior Art> As is well known, the front frame of a pachinko machine is equipped with a game ball firing mechanism so that the player can adjust the number of game balls fired, the strength of the balls, etc. Also provided is an operation handle, which is a firing mechanism operating section for controlling the operation of the game ball firing mechanism.

The game ball firing mechanism, ball tray, game ball supply tray, etc. installed on this front frame do not need to be replaced when replacing the game board, so the front frame can be used even if it is discarded due to aging. It is envisaged in the future that all mechanisms other than the game board and the electrical control device for controlling the electrical game equipment provided on the game board will be permanently installed together with the island equipment.

<Problems to be solved by the invention> However, the life of the firing motor and rotary solenoid, which are the driving sources of the firing mechanism provided in the front frame, is short compared to other mechanisms, and the upper leg movement is short. When the tip of the launcher for game balls driven by a power source wears out, the ball tends to fly unevenly, making it impossible for the ball to fly to the player's desired location. As a sprinter deteriorates over time, problems occur such as hitting the ball strongly or not being able to hit it.

Therefore, if it becomes necessary to replace the game ball launching mechanism or the firing mechanism, the front frame itself must be replaced, which is extremely uneconomical and also poses a major obstacle to making the front frame a permanent fixture.

Therefore, it has been desired to develop a pachinko machine in which only the game ball firing mechanism and the firing mechanism operating section can be replaced.

<Means for solving the problems> The present invention has been proposed in view of the above, and consists of an upper horizontal member (3), a lower horizontal member (4), a left vertical member (5), a right vertical member, and A frame body (8) having a window (7) by connecting vertical members (6) in a rectangular shape.
